The Single-Number Formula
Instead of micromanaging 15 budget categories, calculate your Safe Daily Runway:
$\text{Daily Limit} = \frac{\text{Salary} - (\text{Rent} + \text{EMIs} + \text{SIPs} + \text{Fixed Bills})}{\text{Days Remaining in Month}}$
Example: The ₹75,000 Salary
- Fixed Rent & EMIs: ₹30,000
- SIPs & Goals: ₹15,000
- Utility Bills & Cook: ₹6,000
- Remaining Flexible Cash: ₹24,000
- Daily Safe Limit: ₹800 / day
If you spend ₹300 today on lunch, your daily limit for the rest of the month climbs to ₹817. If you spend ₹2,000 on a Saturday dinner, it adjusts to ₹760. You always know your exact pacing without complex spreadsheets.
